Light Transition Metal Functionalized ψ‐Graphene as Promising Hydrogen Storage Architecture

Advanced Energy and Sustainability Research, EarlyView.
ψ‐Graphene monolayers doped with Sc, Ti, or V exhibit strong metal binding, low diffusion barriers, and high reversible hydrogen storage capacities. Density functional theory and AIMD analyses confirm their thermal stability and compliance with U.S. DOE targets.

The loop-by-loop Baikov representation — Strategies and implementation

Journal of High Energy Physics
In this paper, we discuss the Baikov representation of Feynman integrals in its standard and loop-by-loop variants. The Baikov representation is a parametric representation, which has as its defining feature the fact that the integration variables are ...

Nucleic Acid‐Based Molecular Machines for Biological Applications

Advanced NanoBiomed Research, EarlyView.
Molecular machines are devices assembled from molecules with specific functions. In this review, the development of DNA nanostructures, which are then assembled into molecular machines, is summarized. Their classification and biological applications, such as biosensing, targeted therapy, and molecular circuits are introduced.

Calabi-Yau Feynman integrals in gravity: ε-factorized form for apparent singularities

Journal of High Energy Physics
We study a recently identified four-loop Feynman integral that contains a three-dimensional Calabi-Yau geometry and contributes to the scattering of black holes in classical gravity at fifth post-Minkowskian and second self-force order (5PM 2SF) in the ...

Relationships among transforms, convolutions, and first variations

International Journal of Mathematics and Mathematical Sciences, 1999
In this paper, we establish several interesting relationships involving the Fourier-Feynman transform, the convolution product, and the first variation for functionals F on Wiener space of the form F(x)=f(〈α1,x〉,…,〈αn,x〉),

Quantum GraviElectro Dynamics

Annalen der Physik, EarlyView.
The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

A change of scale formula for Wiener integrals on abstract Wiener spaces

International Journal of Mathematics and Mathematical Sciences, 1994
In this paper we obtain a change of scale formula for Wiener integrals on abstract Wiener spaces. This formula is shown to hold for many classes of functions of interest in Feynman integration theory and quantum mechanics.

Decomposition of Feynman integrals on the maximal cut by intersection numbers

Journal of High Energy Physics, 2019
We elaborate on the recent idea of a direct decomposition of Feynman integrals onto a basis of master integrals on maximal cuts using intersection numbers.

Insights Into Improving the Li‐Ion Transference Number and Li Deposition Uniformity Toward a High‐Current‐Density Lithium Metal Anode

Carbon Energy, EarlyView.
A Li‐ion conductivity‐enhancing separator (PCELS) based on polymer, ceramic, and electrically conductive materials is proposed to improve Li‐ion conductivity and regulate Li‐ion flux. The PCELS has high electrolyte wettability and Li‐ion transference number.
